After the Hunt

BROADHEADS: There have been some questions concerning the use of
mechanical or "open upon impact" broadheads. They are legal to
use in Oklahoma as long as they are at least 7/8 inches wide
when they open on impact.

Crossbow / Mechanical Bow Draw Device Usage - The use of
crossbows and conventional longbows with a device that permits
the bow to be held mechanically at full or partial draw are
legal hunting methods during any open season when conventional
longbows (archery equipment) are a legal means of take. See
individual species’ regulations for any draw weight, bolt length
and broadhead size requirements.
